    Test ConditionsThe following setup and environmental conditions are required to ensure the PXIe-5632 meetspublished specifications. Keep cabling as short as possible. Long cables and wires act as antennas, picking up extra

    noise that can affect measurements. Verify that all connections, including front panel connections and screws, are secure. Maintain an ambient temperature of 23 C 5 C. Keep relative humidity between 10% and 90%, noncondensing. Allow a warm-up time of at least 45 minutes after the chassis is powered on and NI-VNA

    is loaded and recognizes the PXIe-5632. The warm-up time ensures that the PXIe-5632and test instrumentation are at a stable operating temperature.

    In each verification procedure, insert a delay between configuring all instruments andacquiring the measurement. This delay may need to be adjusted depending on theinstruments used but should always be at least 1,000 ms for the first iteration, 1,000 mswhen the power level changes, and 100 ms for each other iteration.

  • Ensure that the chassis fan speed is set to HIGH, that the fan filters, if present, are clean,and that the empty slots contain filler panels. For more information, refer to the MaintainForced-Air Cooling Note to Users document available at ni.com/manuals.

    Use an appropriate torque wrench or torque screwdriver and SMA driver bit to tighten allmodule RF connectors (SMA or 3.5 mm). NI recommends use of 1 N m (9 lb in.).

    Use a 3.5 mm torque wrench (8 lb in., NI 781615-01 or equivalent) to tighten 3.5 mm or2.92 mm (K) connections without an SMA connector.

    Initial SetupRefer to the PXIe-5632 Getting Started Guide for information about how to install thesoftware and the hardware and how to configure the device in Measurement & AutomationExplorer (MAX).

    Test System CharacterizationThe following procedures characterize the test equipment used during verification andadjustment.

    Caution The connectors on the device under test (DUT) and test equipment arefragile. Perform the steps in these procedures with great care to prevent damagingany DUTs or test equipment.

    Zeroing and Calibrating the Power Sensor1. Ensure that the power sensor is not connected to any signals.2. Zero and calibrate the power sensor using the built-in functions in the power meter,

    according to the power meter documentation.

    Performing User Calibration on the PXIe-5632Allow a 45 minute warm-up period before you begin a user calibration.

    The PXIe-5632 includes precise internal circuits and references used during user calibration toadjust for any errors caused by short-term fluctuations in the environment.

    Note You must perform different user calibrations before verifying certainPXIe-5632 specifications.

    The following verification procedures require you to perform either an automatic or manualport one reflection user calibration or a transmission frequency response user calibration priorto the completion of the verification procedure: System Dynamic Range Corrected Directivity (300 MHz to

  • Corrected Directivity (5 GHz to 8.5 GHz) Corrected Source Match (5 GHz to 8.5 GHz)
